Unless you're making your arrows or hot melt glue was used to glue in the inserts you will not be able to line up the broad heads. I wouldn't be too concerned with that as the arrow flight will be your guide anyways. After getting a dozen shoot them all picking out 6 that fly the best and use them for your hunting needs. Most carbon arrows are built with fast setting glues similar to super glue. Muzzy broad heads are known for their accuracy and toughness. When I shot recurve bows I would line up the feathers and broad heads probably more for my own piece of mind rather than any other merits.
